Formula

The discount factor is a decimal number that represents the present value of $1 received at a future date. It is fundamental to discounted cash flow (DCF) analysis, net present value (NPV) calculations, and bond pricing.

DF = 1 / (1 + r/n)^(n×t)

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter the discount rate (annual percentage).
2Enter the time period in years.
3Choose the compounding frequency.
4Optionally enter a future cash flow amount to see its present value.

Examples

10% discount rate, 5 years, annual compounding

1.DF = 1 / (1.10)^5
2.DF = 1 / 1.61051 = 0.62092
3.PV of $10,000 = $10,000 × 0.62092 = $6,209

Result: 0.620921

Frequently Asked Questions

A discount factor is a decimal between 0 and 1 that represents the present value of $1 to be received in the future. It declines as time increases or as the discount rate rises.

Multiply any future cash flow by the discount factor to find its present value. This is the core of DCF analysis and net present value calculations.

The discount rate should reflect the opportunity cost of capital or required rate of return. Common rates are 8-15% depending on risk and industry.
